Question

1. what is the velocity of a pendulum when it is at its maximum amplitude on either side?

○ 1
○ 100
○ 0
○ 50

Explanation:

Step1: Analyze energy conversion

A pendulum swaps between kinetic energy ($KE=\frac{1}{2}mv^2$) and gravitational potential energy ($PE=mgh$).

Step2: Max amplitude energy state

At maximum amplitude, the pendulum stops momentarily to reverse direction. All energy is potential, so kinetic energy is 0.

Step3: Solve for velocity

Set $KE=0$: $\frac{1}{2}mv^2=0$. Since mass $m
eq0$, $v=0$.

Answer:

0
